To all whom it may concern:-

Be it known that I, JOSEPH H. JACKSON, a citizen of the United States,and resident of Hamilton, in the county of VVentworth and Province ofOntario, Canada, have invented new and useful Improvements in Type-Writing Machines, of which the following is a specification.

My invention relates to improvements in typewriting machines, in which asegmental carrier carrying a series of type arms fulcrumed thereto issuitably mounted in the machine, and is adapted to carry said type inconsecutive order to writing position to and at right angles to theimpression roller, or platen, by the operation, or the depression of akey.

The objects of my invention are, first, to provide a machine, in whichthe type is carried to one common center in the segmental carrierand-therein positioned; second, to

provide means for engaging thet pe with the impression surface bypressure, t iird, to provide a silent and noiseless typewriter while thesame is in operation, fourth, to provide 'means for allowing the upperor lower case of type to be operated by pressure against the impressionsurface, fifth, to afford facilities for bringing type to position andforwarding the same at right angle to the impression surface at onenoiseless operation, and sixth, to provide means for attaining equalizedpres-' sure of the type. I attain these objects by the mechanismillustrated in the accompanyingFdrawing in which: i igure 1, is asectional side of the machine, and in normal position. Fig. 2, is a planof the same. Fig. 3, isan enlar ed detail sectional elevation of themova 1e segmental type carrier showing mechanism for adjusting t e typeshifting block. -Fig. 4, is an enlarged side elevation of a type arm,with the type. Fig. 5, is an enlargedplan 0f the central-part of thetype carrier.

Similar letters refer to similar parts throughout the several views.

.In the drawing the frame work of the machine is indicated by A, and isstationary.

B, is the impression surface or roller mounted on the movable carrier O,which is adapted to slide on the horizontal rails D .of the frame A.

E, is the segmental carrier to which the type arms are fulcrumed, and ismounted on type arms J, as shown.

being hinged to the transverse bar a of the frame A, and the lower endof the arm H, is hinged to a centrally located lug 2, of the frame. Thearms F, and H, support the segmental carrier E, and move in parallelorder to bring the carrier E on a level plane toward the impressionsurface B, and at right angle thereto. The segmental series of type armsJ, are fulcrumed to the segmental wire K, which is secured in thecarrier E, which moves at right angle to the impression surface. Theopposite ends of the type arms J, are provided with the type P, whichare adjustably secured to ,the type arms, by means of a tapered shank 3,on t type, said shanks fitting in the sockets 4, of t e arms, andsecured thereto by nuts or screws 5.

The face of the type are convexed and of a circle whose center 1s thesegmental fulcrum 'wire K, to which the ty e arms are fulcrumed. Theshanks 3 o the type, are a continuation of the type, and have shoulders3,'to fit on the sockets 4. A central type .arm is shown hangingdownward in Fig. 1. of

the drawing, and at rest.

The series of keys M, are fulcrumed at N, to the machine, and are heldto the fulcrum by the suspension springs 6, which connect said keys, andthe bracket 7, of the frame together, the opposite end parts of the ke sM eing held in rest dposition by means 0 the rods R, connecte thereto,and to upper cranks T.

e end of the The carrier E, has an outer segmental fulcrum wire S,similar to the fulcrum wlre K,

and a series of cranks T are hung on the wire S, and the aforesaid rodsR, and pivotally connect the cranks T, and the keys'M, together. LinksU, are pivotally connected to the opposite ends of the cranks T, and tothe A slot 8 is necessary in the type arm, at the connection of the linU, with the arms for operative purposes and to allow the carrier E toarrive at ts predetermined place.

The central art of the segmental carna e E, has a shift b opening, orrecess X, to receive the type P, in

look V, with a central gui e said recess. The recess X is shaped in amaning.

ner to conform to the sides and to the rear part of the type, and ispositive. The block V, has an upper flange, or projection V to retainthe block in lower position in the carrier, as shown.

When a key M, is depressed, the type P, enters the recess X in the shiftblock V. Between the hinges a and 2, of the arms F, and H, is atransverse bar "W, to which the vertical rod 9 is connected, and a lever10, is pivotally connected to the upper end of the rod 9. The oppositeend of the lever is pivotally connected to the link 12 which is hingedat 13, to the wall A, of the frame. The lever 10, has an upper arm 14,to which is pivotally connected a needle 15, and the opposite end of theneedle enters into a hole 16 inthe shift block V, and the point of theneedle enters one of the needle point holes 17 shown in broken lines inFig. 4 of the dr2fwing, in the rear of the type P, when the type is inposition in the recess X of the block V, for writing. The lever 10 isfulcrumed to the lug 18, of the carrier E.

When the rod 9 is brought downward by the depression of a key M, on thetransverse bar W, the lever 10, and the link 12, come in line with eachother, consequently the carrier E, on the arms F, and H, is carriedtoward the platen B, and at the same time the type arm J, is brought toposition and the type P, enters the recess X of the block V, and theneedle on the arm 14 enters a hole 16 in the block V, and locks it andalso enters the needle point hole 17, in the type, to lock the type, andat the same time to print against the im ression surface.

20, is a shift bloc key, at one side of the key board, and is fulcrumedat 21, to the side of the frame A, and is held at tension by the spring6 which is hung from the bracket 7. A small lever 22 is fulcrumed at 23to the carrier E, and one end of the lever 22 is pivotally connected toa'connecting rod 24, and the opposite end of the lever 22 is ivotallyconnected to a lug 25 depending om the ortion V of the shift block V asshown in ig. 3. The lever 22 operates in a slot 30 in the carrier E,shown in Fig. 5, of the draw- Thelower end of the rod 24, is pivotallyconnected to an arm 25, which is centrally located, and a similar arm 25is provided, the arms being disposed at a distance apart from each otherand both arms 25 secured to a loosely mounted transverse rod 26. centralarm 25, the rod 24 is connected, and to a similar arm 25, the rod 28 isconnected, and the lower end of the rod 28 connects with a key 20.-

When the key 20 is depressed, the block V, in the center of the carrierE, is shifted upward until the lower hole 16in the block V is osite tothe needle 15 cushion 38 is disposed beneath the arms To the M and 20 inthe frame A, to receive the impact of the arms and thus insure an equalde- Upon the depression of a key M, a rod R is brought downward,consequently the crank T, and the link U raises the type arms J,together with the type P on the broken arc line 32, as shown in Fig. 1of the drawing. Immediately after the type P has entered the one commonand central recess point X in the block V, the rod 9 is brought downwardby means of the key which presses on the transverse bar thereby causingthe lever 10 and the link 12 to be brought into alinement with eachother, consequently the arm 14 of said lever 10 propels the needle 15through the hole 16 in the block V, and the point of the needle into theopening 17 which conforms to. this needle point. At the same depressionof the key, the segmental carrier E on the three hinged arms F, F, andH, is brought toward the platen B by means of the alinement of the lever10 and the link 12 forwarding the lug 18, hence also forwards thecarrier E, of which said lug forms a part, to a predetermined lace.

It will be noticed that all the type J ente the block V, in writingorder as one common center, which is the center of the fulcrum wire K ofthe type arms J, and that each type P is adjusted in the socket 4 of thearms, in order that the type shall all be in the same direction, thatis, opposite to the platen or impression surface B. The lower end/of theopening, or recess X, in the shift block V, is of sufficient size toallow the type of all the arms J, to freely enter the recess X. Eachtype is minutely adjusted and set in its socket 4 and held by the screw,or nut 5 on the end of the shank of the.typ'e.

It will be obvious that the type arms J, the carrier E, together withthe type locking needle 15, are all moved together to perform theirseparate functions by one depression of any one of the series oftypewriting keys, and that the carrier E moves at right angle to theimpression surface.
